'Lake retention time' (or residence time of lake water) refers to measurements based on the volume of water in a lake and the average rate of outflow. It represents the amount of time it takes for a substance introduced into a lake to flow out of it again. This metric depends on a number of factors, including lake volume, number of rivers flowing in and out of the lake, and average depth. The retention time is especially important where pollutants are concerned.
